"He's great and doing really well," sources close to the actor told omg! about how Zac is today. "He's really focusing on his career. You would have no idea he even had a problem by looking at his behavior today."

This week, false reports circulated that Zac collapsed after a supposed "heroin overdose," although omg! has learned there is no truth to that allegation.

However, Zac did reportedly abuse cocaine and Molly, a form of Ecstasy, which is why he got help. And we're glad he did, because he appears to be better than ever.
